<h1 class="topictitle1">FusionOne Compute节点故障导致备份恢复任务失败</h1>
<div><div class="section"><h4 class="sectiontitle">现象描述</h4><p>备份或恢复FusionOne Compute虚拟机过程中，VRM管理节点故障，发生主备节点切换，出现备份或恢复任务失败。</p>
</div>
<div class="section"><h4 class="sectiontitle">可能原因</h4><p>FusionOne Compute管理节点采用双节点主备架构部署时，发生硬件、关键进程挂起、OS崩溃、网络中断等故障时，备用节点需要1~2分钟才能完成业务接管（根据环境实际负载情况可能会耗时2~3分钟），接管过程中，管理服务处于异常状态，接口无法正常调用。</p>
</div>
<div class="section"><h4 class="sectiontitle">处理步骤</h4><ol><li><span>检查FusionOne Compute管理节点是否恢复。</span><p><p>通过<strong>https://</strong><em>FusionOne Compute管理节点IP地址</em><strong>:8443</strong>登录FusionOne Compute界面，如果能正常登录，则说明FusionOne Compute管理节点已恢复。</p>
</p></li><li><span>待FusionOne Compute管理节点恢复后，重新执行备份或恢复任务。</span></li></ol>
